Sub-micron, roundness below 0.3 μm

Hydrostatic Spindles

Our built-in motor hydrostatic spindles represent the peak of rotational accuracy. Integrating the motor directly into the hydrostatic bearing housing eliminates external drive vibration. The oil film carries the shaft with no mechanical contact — no wear, near-zero vibration, and sub-micron precision for the most demanding grinding and boring work.
